ma page de démarrage change, meme en activant hijack blaster

Bonjour, ma page de démarrage sous IE était le site officiel de Targa (j'ai jamais changé cette page étant donné que j'utilise firefox)

Mais depuis hier, mon antispyware m'indique que ma page de démarrage sous IE s'apprete à être changé, et me edmande donc "allow ou block" naturellement, je block, mais rien à faire, ca me change quand même et me renvoie vers le site de msn.

J'ai donc fais un log avec hijackThis rien d'anormale (à mes yeux), et même en lancant Browser hijack blaster , la page se remet toujours sur celle de msn.

Voici mon log avec hijackthis :
